Like pretty much everyone, I am frustrated by bad calls that adversely affect my team. However, it has always been part of the game and I have learned to live with it.
What really infuriates me is bad calls that get reaffirmed by a video review, or a GOOD call that gets overturned by a video review. There are bang-bang plays that do not offer conclusive evidence to overturn and that is okay. What is NOT okay are bad calls like that 4th down spot that are first wildly marked poorly by the officials and then confirmed with video review. That 4th down spot was a full 2 yards off, everyone in the stadium knew it, and it still didn't matter after review. Horrible. The overruling of the Ohio State targeting call on Leidner last year will forever be a gripe of mine too.
Critical calls at critical points in a game on critical plays do not "even out." Instead, they chip away at the integrity of the game.
